enzymatic debridement
The use of proteolytic enzymes to selectively remove necrotic tissue while preserving viable tissue in burn wounds.
Full Definition
Enzymatic debridement employs topical enzymes such as collagenase to break down necrotic tissue through proteolysis, offering a selective and less traumatic alternative to sharp debridement. This method is particularly useful for patients who cannot tolerate surgical procedures or when preserving marginal tissue is critical. The process is gradual, requiring multiple applications over several days to weeks. While gentler than mechanical methods, enzymatic debridement requires careful wound assessment to ensure complete removal of devitalized tissue and may be combined with other debridement techniques for optimal outcomes.
Usage
Usage note: Gentler than surgical debridement but slower; requires patient selection and monitoring.
